(CNSNews.com) – In a speech at the Conservative Political Action Conference in Washington on Thursday, former Republican presidential candidate Herman Cain hailed the American Revolution -- and said it’s time for another one.

“It’s time for a new American revolution, not with bombs and bullets but with brains and balance,” Cain said. “We must outsmart liberals. We must outsmart the stupid people running America.”

Cain, who was forced from the presidential race over allegations of sexual harassment and marital infidelity, said he quit the Republican presidential race to “put family first.”

Cain, former Godfather’s Pizza and former president of the National Restaurant Association, surged to the head of the Republican presidential field in late 2011. He told a crowd at the Conservative Political Action Conference on Thursday that he appreciated the support of conservatives.

“There were two reasons I dropped out of the race -- gutter politics, and two, I chose to put my family first,” Cain said.

“In making that decision, I knew we together could change Washington from the bottom up, even if your David didn’t make it to the White House,” he said – a reference to David and Goliath.

Cain also announced that he is endorsing “Joe the Plumber” Wurzelbacher, who is running for the House in Ohio.
